  1. Bone mineral density of combined 12 thoracic (T12) and first lumbar (L1) vertebrae; Data include participants who were not administered a contrast agent; OSA obstructive sleep apnea (apnea–hypopnea index ≥ 5 events/h), TBS time duration between scans, F first scan, S second scan, DIFF difference in HU between second and first CT scans, negative sign indicates a loss in BMD, HU Hounsfield unit. Values are mean ± SD for age and SEM for the remaining parameters.
  2. #p < 0.05, ##p < 0.01 first scan vs. second scan. Statistical differences were determined by a two-tailed t-test.
  3. +p < 0.01, no-OSA vs. OSA, statistical differences were determined by a 2-way repeated measurements ANOVA.
